Others have already talked about Blue Apron. The NPR podcast How I Build This released an episode on April 1 with the Stitch Fix founder, Katrina Lake which was quite interesting. Stitch Fix has quite a team of data scientists working on their recommendation system. They typically send about 5 items per shipment, so they need to be very confident the 5 will fit, you'll like them, and you'll like the price. With Spotify or Netflix, the user can browse around and can skip between songs or shows quickly. If their recommendation engine wasn't phenomenal, it'd still be a viable product. Stitch Fix typically has 1 shot per month to sell you stuff you care about.
